IC Package Design Engineer (Flip Chip/Substrate)

UST Malaysia; Bayan Lepas; On-site; MYR 150,000 - 240,000; Full time

Job summary

UST Malaysia is seeking a highly skilled Package Design Engineer with 5–8 years of experience in advanced IC packaging to design multi-layer substrates (8+ layers) and Flip Chip packages. You will lead layout, stack-up planning, and tooling with Mentor Graphics and Cadence Allegro, ensuring manufacturability and reliability.

You will collaborate with SI/PI/thermal teams and vendors to optimize performance, and travel for on-site support as needed at OSATs and substrate suppliers.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Electronics, Materials Science, or related field.
• 5–8 years of hands-on experience in package design, with proven expertise in multi-layer (8+) substrate design.
• Proficiency with EDA tools: Mentor Graphics (Preferred), Cadence Allegro, PLA (Mentor Graphics Xpedition / Cadence Allegro Package Designer).
• Strong knowledge of substrate manufacturing rules and assembly rules.
• Experience with Flip Chip package design methodologies.
• Familiarity with SI/PI/thermal considerations in advanced packages.
• Strong communication and collaboration skills for cross-functional and vendor engagement.
• Willingness to travel and provide on-site vendor support.

Responsibilities

• Perform the design and development of multi-layer package substrates (8+ layers) for advanced semiconductor devices.
• Perform package layout, routing, and stack-up planning using EDA tools (Mentor Graphics, Cadence Allegro, PLA).
• Ensure designs comply with substrate manufacturing rules (trace width/spacing, via design, impedance requirements).
• Incorporate assembly rules (die placement, bump/ball pitch, solder joint reliability, warpage control) into package designs.
• Develop and validate Flip Chip package designs, including bump assignment, redistribution layers (RDL), and underfill considerations.
• Collaborate with Signal Integrity, Power Integrity, and thermal analysis teams to ensure robust performance.
• Partner with substrate vendors and OSATs to verify design manufacturability, yield, and assembly feasibility.
• Provide on-site vendor support when required to resolve design and assembly issues.
